RTV900 Tweaks

[Dargo]

Not that I don't believe you Jesse1, but I've run a tractor at night, as well as my RTV, and I've never seen anything come out of the exhaust that was on fire. Now on my Cummins Diesel powered Dodge truck, when it was on the dyno a few months ago I could have sworn it was breathing fire. It produced 396 hp and 1012 ft. lbs. of torque! /forums/images/graemlins/cool.gif

You see, I need that sort of power to haul my tractor and RTV. (at least that is what I tell my wife /forums/images/graemlins/blush.gif)

It's probably not as noticible if an engine has a turbo, but flakes of red-hot carbon will blow out-- that's probably the reason the Forest Service requires a flame arrestor. I've seen sparks fly from the exhaust on the 990 David Brown tractor I had 20 years ago-engine was non-turbo.

Flame out the exhaust was common on the older non-turbo diesels in trucks, especially if the fuel had been turned up on the engine. My Dad drove a '59 White Diesel that had a 220 Cummins. It was very common to see a foot of flame coming out the stack when the engine was working hard. In fact, he had a mirror aimed so he could see the stack- too much flame meant to back off on the throttle!

This is odd - according to the RTV900 service manual it already has a US Forest Service approved spark arrestor muffler. Why would they be putting on this extra spark arrestor on the end of the tailpipe? I didn't check but maybe the vehicles with the tailpipe spark arrestor just have a conventional muffler without the clean out hole.

I've attached the page out of the manual.

Dargo,

I hope you have a manual tranny in that Dodge! I had a Dodge with cummins that I "tweaked", and it was producing 375 hp and 1200 lbs of torque. The automatic trans would last no more than 15000 miles!

 

[Dargo]

DieselMule, the tranny is automatic and I can roll smoke off of all 4 rear tires practically at will. Also, it is warranted for another 2 years or 40K miles. Oh, did I tell you that it isn't stock either? /forums/images/graemlins/grin.gif It is a rather pricey ATS Stage IV full race setup. It was built with the intention of adding twins under the hood. No twins yet, but they are on the list... /forums/images/graemlins/wink.gif

Wow, you guys are observant! That's actually a "typo" till the muffler is certified by itself...they all have the removable plugs for cleaning. The add-on spark arrestor is a temporary thing, so it really isn't a "typo" now with the add-on.

 

[Dargo]

No "typo", huh? It states that this procedure should be done for the "lift" of the vehicle in the manual? /forums/images/graemlins/blush.gif What is the "lift" of the vehicle?? /forums/images/graemlins/wink.gif

 

[Ricochet]

Huh? /forums/images/graemlins/confused.gif Maybe my last reply didn't make sense. /forums/images/graemlins/smirk.gif

I believe Kubota meant to say "for the LIFE of the vehicle".
